Detecting changes in XML in oracle XML DB

Is there a utility, function etc., in Oracle XML DB that checks the changes between two stored XML in XMLType table?

This feature is introduced in 11g. See XMLDIFF and XMLPatch

SOAP oracle xml sql utility class definition not found error

I have created a java class that connects to database using JDBC runs an sql statement and produces xml using Oracle XML SQL Utility class. The java class works perfectly when I deploy it as a soap web service and try to run through SOAP server it gives a SOAP error oracle/xml/sql/query/OracleXML/Query [java.lang.NoClassDefFoundError].
Can anyone help please.
Thanks
Alina

Sounds like you have not included the xsu12.jar file in the server-side CLASSPATH.
This depends also on the xmlparserv2.jar and on the Oracle JDBC driver. Later versions
of XSU may also depend on the xdb.jar file, too.

New to XML and Oracle

Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
Mike

Hi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

Oracle XML DOM parser - attribute values are not printing on the screen ??

Hi Everyone,
I am just trying to use oracle DOM parser to paerse one of my xml file, java file can be compiled and run agianst a xml file, But I cannot see any attribute values printing on the screen..
Appreciate if anyone can help, where I have gone wrong please?
Below is the java file:

How to print Barcode data in Oracle XML Publisher Report

Hi,
We have an rdf report which prints Bar code in the starting page based on a custom procedure from MarkView. It works well with Oracle Reports.
But since the current report was a matrix report, we are changing it to a Linear report through Oracle XML Publisher Report.
We have all the things possible in the new Oracle XML Report.. But we are unable to print the Bar code data which is BLOB in the XML Report..
Can anyone help me on this? We have UAT dates around the corner..
We have an RTF Template .
Help asap.
Thanks
Abhilash

first thanks for your reply,
i already figured that out and deployed it using 10.1.3.1 jars
my question
1) if it is a bug , how come it works fine with jdeveloper (
i would appreciate if you could provide any info about it.
2) i dont want to sound sarcastic , but 10.1.3.1 has of optimistic locking and the recommended solution i found was to use descriptor.getQueryManager().setUpdateCallCacheSize(0);
looks like 10.1.3.1 fixed one bug and introduced other one which was working fine earlier...
is there any other way of fixing optimistic locking issue other than using the
descriptor.getQueryManager().setUpdateCallCacheSize(0);
where i can find the latest/greatest (up to date patched version of toplink)
thanks again for your help

Getting oracle.xml.parser.v2.XMLParseException: Start Of root Element

Hi All,
I am getting below error while creating STUB/Skeleton in Jdeveloper to call a web service from OAF Page But getting below error while trying to creating Stub/Skeleton to call weservice
ERROR:
oracle.xml.parser.v2.XMLParseException: Start Of root Element
Any suggestion on This
P.S: I am calling a third party web service so can not able to make changes in XML
Regards,
903096

Possibility is that there is a problem in the XML that is being passed. Can you double check with the third party software? Also check if you can try it outside OA Framework first and then if its tested you can integrate with EBS.

Oracle.xml.parser.v2.SAXParser error

I'm reposting this error that I recently received one more time before removing the XML transforms from my Java projects and doing them in .NET.
Code that was working fine suddenly getting a transform error using JDeveloper.
Get the following:
javax.servlet.ServletException: javax.xml.transform.TransformerConfigurationException: XML-22000: (Fatal Error) Error while parsing XSL file (weblogic.xml.jaxp.RegistryXMLReader cannot be cast to oracle.xml.parser.v2.SAXParser).
at weblogic.servlet.jsp.PageContextImpl.handlePageException(PageContextImpl.java:417)
Seems that

will not transform XML to HTML via XSL in JSP anymore.
If I run the XSL i get the HTML results I expected in an HTML test page.
So I know the XML and XSL is sound.
XSL and DOM parsing in Java/Oracle was a major pain in the ass in the first place and now this.
Well I've spent hours going through Oralce/Java documentation on XML, DOM and XSL transforms.
All that time spent and still so unstable. I don't think I was ever able to really get what I wanted
which was to transform my XML document to HTML, update via JSP and have the XML document
be updated and ready to view in a summary page. The XML document changes were never really
available unless I closed the app and restarted. So all in all a failure of capabilities compared to my
use of XML in .NET.
So........
Me thinks it will be a good idea to take out the transforms and have my JSP use a script to invoke a
method in a class that extracts it from a message. Just have PL/SQL interface with XML and do the
transform or serialize thing there.
I don't want to give up on XML but I'm tired of trying to jam a square peg into a round hole
with Java and JDeveloper.

We don't support file references ("cv1_0.dtd"). Only url type references
are supported, of the form:
@ <!DOCTYPE cv1 SYSTEM "http://www.oracle.com/public/cv1_0.dtd>
Note that the url should be accessible to the world without the need to authenticate.
you could put your dtd in the "public" area in your iFS system.

Oracle.xml.sql.OracleXMLSQLException when using OracleXMLQuery getXMLDOM()

Hi!
I am trying to reuse a code in JDeveloper to get XML from a query. I have copied the code from a method and created a new method with the copied code and changed it. The problem is that when I run the old code I now get following error:
Ett oförväntat fel har inträffat: Application: FND, Message Name: FND_GENERIC_MESSAGE.
Tokens: MESSAGE = oracle.xml.sql.OracleXMLSQLException: Det här objektet har stängts.
Vill du inte att objektet ska stängas automatiskt mellan anropen kan du granska metoden 'keepObjectOpen()'.;
This means in english something like:
An unexpected error accoured: Application: FND, Message Name: FND_GENERIC_MESSAGE = oracle.xml.sql.OracleXMLSQLException: This object is closed. If you don't want the object to close automatically between calls you can check method 'keepObjectOpen()';
the code I'm running is:
public String punchoutSomething()
throws Exception
StringBuffer sqlForXml =new StringBuffer("select pv.*"
+", cursor(select * from XXPOS_PUNCHOUT_TABLE2 c where c.vendor_id=pv.vendor_id) as contacts"
+" from XXPOS_PUNCHOUT_TABLE1 pv where vendor_id in (");
// add all ids
SuppSummVOImpl vendorView = getSuppSummVO();
Row row;
int punchoutCnt=0;
// vendorView.reset();
Row[] selectedRows = vendorView.getFilteredRows("SelectStatus","Y");
for(int i=0;i<selectedRows.length;i++)
if(punchoutCnt>0)
sqlForXml.append(",");
sqlForXml.append(((Number)selectedRows.getAttribute("VendorId")).toString());
punchoutCnt++;
if(punchoutCnt==0)
sqlForXml.append("-1"); // make sql valid, will not return rows
sqlForXml.append(")");
// System.out.println(sqlForXml); // DEBUG

, sqlForXml.toString()
xq.setRaiseException(true); // in case of error raise an exception (default
// is to generate an error document
xq.setEncoding("UTF-8"); // not necessary?
xq.useLowerCaseTagNames();
xq.setRowsetTag("vendors");
xq.setRowTag("vendors_row");
//System.out.println(xq.getXMLString()); // DEBUG
XMLDocument suppl = (XMLDocument)xq.getXMLDOM();
XSLProcessor xslt = new XSLProcessor();
InputStream sheetStream = this.getClass().getResourceAsStream("mystylesheet.xsl");
if(sheetStream==null)
throw new Exception("Could not load stylesheet");
XSLStylesheet sheet = xslt.newXSLStylesheet(
sheetStream
StringWriter serialize = new StringWriter();
xslt.processXSL(sheet,suppl,new PrintWriter(serialize));
String returnXML = serialize.getBuffer().toString();
// System.out.println("X:"+returnXML); // DEBUG
sheetStream.close();
return returnXML;
===================
i've copied the same code into another method and only changed the sql-statment to be used and the stylesheet to use to transform the xml. Is something wrong with that?
Another question: if the xsl refers to a xsd but wihtout any path where should it be?
Thanks for the help,
Patricia

Actually, having looked at Metalink, seems that although this message may be accurate and correct,
it has been 'introduced' as part of the 9i JDBC driver.
So, I used the 8i JDBC driver I happened to have instead and that worked fine.

Oracle XML / XDK has nightmarishly bad performance

Just wanted to share the results of some testing I've done recently. Thought you would all enjoy this information.
[JAVA_HOME is JDK1.4.2_04]

[xdk_version_10.1.0.3.0_production which comes with JDev 10.1.2]

Literally, the only difference is the XML libraries being used for the transformation. Same exact input xml & xslt files and Java code. And the time difference is 1.5min (Saxon) vs 189min (Oracle). Even the Sun JDK libraries are no slouch vs Oracle XDK at just over 4mins.
We might be doing something in our XSLT that is particularly "bad" for Oracle, but I'm not sure of specifics, I just know these results show Oracle to be the wrong choice for our specific transformations and messages.
(The test file is about 20mb XML and the XSLT is quite simple.)
I'll try this experiment again when 10.1.3 is final and see if things are improved. For now, I'd advise anyone considering XDK to also evaluate other XSL engines!!

Sure, here's the code, just modified TraxExamples.java from the Saxonb8-6 release (samples/java/TraxExamples.java) by swapping in my own XML and XSL files instead of the ones that are included with Saxon8.
* Show the simplest possible transformation from File
* to a File.
public static void exampleSimple2(String sourceID, String xslID)
throws TransformerException, TransformerConfigurationException {
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer transformer =
tfactory.newTransformer(new StreamSource(xslID));
System.out.println("TransformerFactory is: " + tfactory.getClass().getName());
System.out.println("Transformer is: " + transformer.getClass().getName());
transformer.transform(new StreamSource(sourceID),
new StreamResult(new File("exampleSimple2.out")));
I simply added my own call to this method using my own file strings and named it "wayne2" so I could call it directly.
Then as you can see above, I simply changed the JAR files in my classpath before executing the tests. Otherwise, everything in the various tests is identical.
I can probably post the XSLT and a sample XML file if there's enough interest. I don't see a simple way to attach a file to a message in this forum...

- resolveNamespacePrefix( find the namespace definition in scope
for a given namespace prefix )
New APIs in the following classes:
1. oracle.xml.parser.v2.XMLNode
- selectNodes( Selects nodes from the tree which match the given
pattern; client can provide an NSResolver implementation to
resolve namespace prefixes in the pattern ).
2. oracle.xml.parser.v2.ElementDecl
- getParseTree( Returns the root Node of Content Model parse
tree, which could then be traversed node by node using

Performance issues - which oracle xml technology to use?

Our company has spent some time researching different oracle xml technologies to obtain the fastest performence but also have the flexibily of a changing xml schemas across revs.
Not registering schemas gives the flexibity of quickly changing schemas between revs and simpler table structure, but hurts performance quite a bit compared to registering schemas.
Flat non xml tables seems the fastest but seeing that everything is going xml, this doesn;t seems like a choice.
Anyhow, let me know any input/experience anyone can offer.
here's what we have tested all with simple
10000 record tests, each of the form:
insert into po_tab values (1,
xmltype('<PurchaseOrder xmlns="http://www.oracle.com/PO.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.oracle.com/PO.xsd
http://www.oracle.com/PO.xsd">

<Price>2550</Price>

<Price>350</Price>

</PurchaseOrder>'));
we have tried three schenerios
-flat tables, non xml db
-xml db with registering schemas
-xml db but not registering schemas, just using XmlType
and adding oracle text xml indexes with paths to speed up
queries
now for the results
- flat tables, non xml db (we where thinking of using it like this to ease fetching of data for ui views in ad hoc situations, then have code to export the data into
xml, is there any oracle tool that will let me
export the data into
xml automatically via a schema?)

ANN: Oracle XML Parser for Java v2.0.2

The new version of the Oracle XML Parser for Java v2 is
available for download and has the following features and
changes:
1. Conformance to the XSLT/XPATH August WD.
Note that there are several changes between April99 XSLT draft
and the August99 XSLT/Xpath draft and these changes have been
implemented in the XSL Processor. The XSL Processor has been
modified to accept XPath syntax for expressions and patterns.
Stylesheets might have to be modified to be conformant to the
August XSLT/XPath draft before they can be used with this
release.
Some of the changes between April draft and the August draft
are:
a. Expressions in the stylesheet must match the XPath
production Expr.
b. Some of the attribute names and element names in XSL
namespace have changed.
c. Some new functions have been added to XPath CORE function
library.
Please refer to the August XSLT/XPath draft for more details.
This is the first production release for v2.

Sending document to oracle xml gateway web service and body is url encoded

Hello,
a question from a complete newbie to web services. I have some code that is sending a soap message to an oracle xml gateway web service. In the soap message the values in the soap body look like &lt ;CNTROLAREA&gt ;
when I would be expecting <CNTROLAREA>. What I have been told is that the content of the ReceiveDocument element has been url encoded which causes the &lt and to correct it I need to change the paramater type from object to xmlnode and to build the request as an xmldocument. The xmlnode and xmldocument comes from a .net guy so I've been trying to find the equivalent in java but am not having any luck. I have a lot of reading to do but was wondering if someone might be able to point me in the right direction on how to correct the problem. I captured the soap message being sent using tcpmon. Why does the body have the &lt instead of the < as I was expecting and is there an xmldocument type? The header part of the soap message looks as I expect. "><soapenv:Header><ns1:XMLGateway_Header xmlns:ns1="http://xmlns.oracle.com/apps/fnd/XMLGateway"><ns1:MESSAGE_TYPE>XML</ns1:MESSAGE_TYPE>. It is being sent as a com.oracle.xmlns.apps.fnd.XMLGateway.XMLGateway_Header type.
thanks
Thanks

The xmlnode and xmldocument comes from a .net guy so I've been trying to find the equivalent in java but am not having any luck. How do you get the data from .net guy? Which interface do you use? What processing do you do after receiving the data?
